| Abstract: | The whole processes of concrete dam construction including concreting, setting and removing of mould,concreting maintenance,variance of surrounding environment and climate,cooling and heat preservation manually, flood control in construction process, transverse gap grouting, reservoir storing,variance of concrete material calorific and mechanic properties with time are simulated. The non-stable temperature field of the dam during the construction period is calculated by using the 3D Finite Element Method, and the characteristics and change rules of the temperature field in the construction period of high arch dam are derived,which can provide references for actual project design. |

| Keywords: | high concrete arch dam construction period temperature field simulation calculation |
